The Veris source side H6812‑1600A‑1V is a large split‑core current transformer used to sense electrical current in a power conductor without disconnecting it. It is designed to clamp around a single conductor carrying up to 1,600 amps of load and produce a proportional low‑level voltage signal (about 1 volt) that can be read by monitoring or metering equipment. Because the core is split, it can be easily installed around an existing cable without interrupting service. The device is typically used for power monitoring, energy management, or protective relay input where accurate current measurement is needed. It operates at standard utility frequencies (50/60 Hz) and provides a safe isolated output for control or instrumentation circuits.
